Question

In Euclidean geometry, the sum of the measures of the interior angles of a pentagon is 540°. Predict how the sum of the measures of the interior angles of a pentagon would be different in spherical geometry.
A.
The sum would be greater than 540°.
B.
The sum would still be 540°.
C.
The sum would be less than 540°.
D.
The sum would less than or greater than, but never equal to, 540°.

Answer 1

In Euclidean geometry, the sum of the measures of the interior anlges of a pentagon is 540°. 

The sum of the measures of the interior angles of a pentagon would be different in spherical geometry because A.) THE SUM WOULD BE GREATER THAN 540°
